First, it's not 100% clear that you booted the installer in EFI mode. If it booted in BIOS mode, it would try to install grub-pc (for BIOS-based systems), which wouldn't work if your firmware is set to boot the hard disk in EFI mode. I doubt if this is the problem, but I thought I'd toss it out as a possibility. You can check your boot mode by dropping to a shell and looking for the /sys/firmware/efi file; if it's present, you've booted in EFI mode. If not, you've probably booted in BIOS mode, although that's not 100% certain.

In any event, at this point your best bet is to do a manual installation of an EFI boot loader. IMHO, GRUB 2 (which is Ubuntu's default) is the worst possible choice; it's flaky and unreliable on EFI systems, in my experience. The easiest to get working is likely to be either ELILO or Fedora's patched GRUB Legacy. If you want to use a 3.3.0 or later kernel, it includes its own built-in EFI boot loader, which is quite reliable and can be very easy to use if paired with rEFInd. My Web page on EFI boot loaders describes all the options and includes installation instructions. Detailing them all here would be impractical.

i would say to consult the arch wiki here:
https://wiki.archlinux.org/index.php/GRUB2
for getting your grub installed. then post back to let me know how you got to your OS.:) i'm trying to setup the same exact thing you are but my grub tries to boot to the lvm root instead of the luks container. if i tell grub to look for the luks container, it does, i enter the passphrase and then it doesn't know where to look for the lvm root!

i gave up with the 12.04.1 Ubuntu 64 bits version install & switch to 12.10 64 bits installer. I followed similar procedure: Create EFI partition in Gparted, name it EFI and set "boot" flag. This time I choosed to align partition to cylinders instead of Mio, so the FAT32 partition is really at the beginning of the disk, don't know if it matters. I'm stuck in 12.10 install after the creation of my Physical volume for encryption and don't know how add create my LVMs inside. Graphical installer seems confusing regarding LUKS + LVM +EFI... I also don't figure out where to set the bootloader.

According to this answer: askubuntu.com/a/250717/95193, UEFI/EFI support would be pushed to a new release and be available on the Ubuntu 12.04.02 daily builds. Do this mean that there's currently NO SUPPORT for UEFI for the 12.04.1 Ubuntu release, could anybody confirm this assessment?

I have been trying to install a dual boot Win8 & 12.04.1 Ubuntu 64 bit on an Asus N56V laptop but did no managed to preform the task (trying different tricks and Linux releases). I have encountered the notorious grub-install fatal error.

I have managed to perform the task by the use of Linux Mint 14 – Nadia (64 bit), but there is a small problem with the Network configuration.

Ubuntu 12.04 is defined as a Long term support release (aimed at 2017) but there are a significant amount of Linus users who encountered problems while trying to install it in parallel to Win 8/7

Should Cannonical consider releasing an upgraded Ubuntu 12.04 which solves the EUFI related issues and newer hardware? This would allow users to benefit from a stable Linux distribution.
